Pre-Start Up
Pressurizing the Fluid Loop
Pressurize the double seal buffer loop or
external seal flush, if applicable, prior to
admitting fluid into the pump casing.
Servicing the Gearbox
Fill the gearbox with lube oil up to a quarter inch
(¼) or 6 mm from the top of the oil level sight
glass.
Note: Prior to using lube oil, verify that it
conforms to acceptable lube oil
s
pec
ification standards. Refer to the
SPECIFICATIONS section in this
manual for more information.
Under normal operation, the lube oil level will
lower about a quarter inch more than when idle.
Additionally bubbles will appear at the top of the
sight glass.
Note: Sundyne recommends that gearbox
lube oil be changed at least every six
months.
For requirement information about priming the
lube oil system, refer to the start-up section in
this manual.
Auxiliary Lube Pump
If your pump includes an auxiliary lubrication
pump, unlock the electrical circuit and move it to
the “hand” position. Check for oil leaks and
recheck the oil level.
Setting the Valves
To set the pump to the designated operating
point, start the pump with the suction valve in
the open position while throttling the discharge
valve.
Operating Conditions
Verifying Operating Conditions
Verify the following parameters against the
specifications on the specification sheet:
•
Suction
pressure
•
Suction
temperature
•
Discharge
pressure
•
Total
head
•
Flow
rate
•
Power
consumption
•
Specific
gravity
•
Viscosity
•
Net Positive Suction Head (NPSH)
The status of these conditions will significantly
alter performance of the pump if they are not in
accordance with the specification sheet.
Check with your Sundyne representative if the
operation conditions of your pump must run
under different parameters than indicated by the
specifications on the specification sheet.
Adjusting the Cooling Flow
If your model pump includes an installed heat
exchanger for the gearbox, adjust the cooling
flow to keep the temperature of the gearbox
sump at 140°-160°F (60°-71°C). Maximum
recommended temperature is 180ºF (82ºC).
